18k. four sapphires? four diamonds
ad dated 1927 http://www.mybulova.com/sites/default/files/uploaded_photos/user2196/0001_18.jpg
Several traits of the low resolution ad are there including but not limited to the Case composition, Jewel count and mention of the Gems.
beautiful piece.
'PANDORA'
an early solid Gold Case which We have seen before sans any Bulova markings inside the back.
When the original image of the Watch is corrected for Camera angle distortion and superimposed over the advertisement We have a match, particularly evident on the Left side of the image.
The Dial appears the same except the elongated 12 and 6 numerals of the actual Watch which can be contributed to Artists rendition issues with the ad (these old ads were formed from drawings which were then transferred to a printing block).
'PANDORA'
Maybe there's a higher resolution version of this ad? I sure can't read the text in the ad Fifth linked above (inserted below) . Based on date of watch 1926 (from movement) and 1927 ad, it sure looks similar it to Pandora., If I could read the text about the Case composition, Jewel count and mention of the Gems, I'd be good with TENTATIVE PANDORA. If someone else can make out the text, I'll take their word for it.
Here is a slightly better look at 'PANDORA'
(how'd this one get by?)
